A good way of thinking of what bullet weight is “ideal” is to consider the balance between one’s ability to hit the vital zone and the size of the bullet needed when it gets there. For the most part, this balance takes one to the lightest weight bullet for a caliber and that happens also to be heavy enough to routinely anchor reasonably well hit game.
The discussions and calculator will help you decide which bullet weight and design class might be most useful for your medium game hunting.
